$700 million convertible - buyers of the note typically will short the stock first since they are covered by the note on the upside, but then it will ramp up. Note convert at $120 per share in 3 to 5 years time frame, forgot which, shows the investors of the note believe stock can go up to $120+. Regardless, this is volatile stock, could easily be $60 or $100 over a short time frame. Look to upside but hangon on the volatility, accumulate at lows and just sell at 90 to 100. If you don't like the volatility, this is the wrong stock to play.
Because this is a CHINESE stock. The Chinese fudge the numbers and people have caught on. They are getting caught over and over exaggerating their profits. Investors are catching on that these stocks are frauds. Look for this stock to be in the 60s very soon. It can't hold the 70s. Mark my words.
